Propane Fuel Cell Reaction

Fuel cells are characterized by their electrolyte material.

Propane fuel cell reaction.

Propane is used as fuel in furnaces for heat in cooking as a energy source for water heaters laundry dryers barbecues and portable stoves. The reaction drives a current and releases protons that then interact with oxygen at the cathode to produce water. Atrex solid oxide fuel cells have been discontinued and are no longer available for sale. Propane is used for patio heaters hot tub heaters furnaces ect.

Like methane propane can be steam reformed albeit at milder temperatures. The methane smr reaction takes place at temperatures of 750 c to 950 c but propane can be reformed to hydrogen at 200 c to 350 c. Density functional theory dft was used to determine propane adsorption energies desorption energies and transition state energies for both dehydrogenation and hydroxylation reactions on a ni 100. A solid oxide fuel cell or sofc is an electrochemical conversion device that produces electricity directly from oxidizing a fuel.

Uses for the products of the reaction. The emissions are water carbon dioxide with the result being higher efficiency minimal noise and safer emissions. For example nonprecious metal catalysts can replace platinum. 6 2 the mcfc principle.

The use of propane fuel in high temperature 120 c polymer electrolyte membrane pem fuel cells that do not require a platinum group metal catalyst is being investigated in our laboratory. The sofc has a solid oxide or ceramic electrolyte. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen usually from air to sustain the chemical reaction whereas in a battery the chemical energy usually comes. The electrolyte is a mixture of alkali metal carbonates typically 62 lithium carbonate and 38 potassium carbonate by molecular proportions a eutectic 1 which melts at 550 c which is heated to between 600 c and 1000 c and in its molten state.

Advantages of this class of fuel cells include high combined heat and power efficiency long term stability fuel flexibility low emissions and. The mcfc has the most complex fuel cell reaction of all the cells available commercially. With only one step a fuel cell directly converts fuel into usable electricity and heat through a chemical reaction. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel often hydrogen and an oxidizing agent often oxygen into electricity through a pair of redox reactions.

Paul breeze in fuel cells 2017. High temperature polymer electrode membrane fuel cells that use hydrocarbon as the fuel have many theoretical advantages over those that use hydrogen. The ultimate products of this reaction are carbon dioxide and hydrogen. Researchers developed a low temperature direct methane fuel cell in 1962.
